Updated August 28, 2022.
For the last several months, I’ve been trying out tons of solid travel toiletries so I can recommend the best to you! Carry-on travelers have been highly restricted with their liquids since 2006, and in 2018, powders came under scrutiny as well. In my own efforts to pack light and always travel carry-on only, I’ve tried tons of brands and products to figure out what’s the best, what’s most efficient, and what’s most effective to take with me when I travel. This guide is here to make things a little easier for you, so I hope it’s helpful!

Liquid Rules
Why do airlines and airports have rules about liquids? Well, in case you never heard about it or have forgotten, there was a plot (perhaps more than one) to create explosives onboard aircrafts using liquid explosives in 2006. So now the good travelers of the world have to be careful about what and how much liquid we bring onboard. The important things to note are:
- You may only bring liquids in containers of 3.4 ounces or less.
- All liquids must fit into one clear, quart-size bag.
- The exceptions to these rules are medical necessities such as contact solution, baby formula, prescriptions, etc.

Soap and Shampoo
This one is pretty common already, but the kind of soap you use matters. I love finding locally-made soaps when I travel, but there are some great ones on Amazon as well! Look for something coconut oil or shea butter, and I prefer soaps made with cold-press process, but that’s totally just a preference! Take a look at these:

*A Note on Dry Shampoo
The soap above is my personal preference for solid shampoo, but dry shampoo is certainly another option! Caution: it may be called “dry” shampoo, but it’s still a liquid inside, so travel size is what you’ll need. It doesn’t work well for me always because my hair is curly, and you have to brush it out. I have, however, used it after straightening my hair to make the straight locks last a couple of extra days, and it worked well! If you have straight hair, toss one in your liquids bag and give it a try. Just don’t forget your hairbrush!

Conditioner
I tried a variety of solid conditioner bars before writing this post, but unfortunately none of them worked well for me at all! My hair felt dry and a bit like straw, so I will continue taking my creamy liquid conditioner with me. After trying so hard to keep my hair long, I don’t prefer the straw look or feel.

Coconut Oil
If you haven’t heard already, coconut oil has about a bajillion uses! It is solid at room temperature, but liquifies at around 75 degrees (or when rubbed between your hands). I’ve looked and looked for a good travel size container that won’t leak in my bag in hot climates, and I just recently found the 2-ounce, refillable jar below, as well as a gravity-feed tube! My favorite ways to use coconut oil are:
- Lotion
- Facial moisturizer
- Hair masque
- Makeup remover
- Shaving cream

Facial Cleanser and Moisturizer
If you’re not a fan of coconut oil but still want a non-liquid makeup remover and moisturizer, wipes are definitely the way to go. They’re convenient for freshening up in-flight as well as keeping neat and tidy wherever you are in the world!

Toothpaste
It’s easy enough to find travel-size toothpaste, but the space in that single, quart-size bag is precious! Make room in your liquids bag by packing these toothpaste tabs instead. Just chew, brush (or swish, if you’re caught without a toothbrush), and spit. Easy! The tablets below are good in a pinch:
If given a choice, however, I would bring Colgate Wisps. They make my whole mouth feel cleaner, and the little toothpick at the end means it can be your dental floss, toothbrush, and toothpaste in one!

Deodorant
I’ve tried quite a lot of deodorants in my time. As someone who works out daily and whose packing mantra is, “I can rewear that,” a reliable deodorant is perhaps the most important thing I pack for every trip!
Natural deodorant is also an important consideration for me because the aluminum and other ingredients in regular deodorants have been shown to cause breast cancer and Alzheimer’s disease, both of which run in my family. There are some decent natural options out there, but I recently found the one that absolutely, 100%, works far better than all the others. It’s called Native, and it comes in several incredible scents for both men and women! Go ahead and get the full-size: it’s solid!

Sunscreen
It’s very important to use sunscreen that works. I have been using Neutrogena for years because it’s one of the few that doesn’t break out my skin in a horrible rash. Just this summer I found their solid sunscreen, so I will never travel with a liquid suncreen again! It works like a dream, goes on smoothly and evenly, and it smells nice, too. This one is zinc-based, so it’s also reef-safe, which is essential for a beach vacation!

Bug Repellent
I’ve been looking for a solid bug repellent for years, and we finally found one! My husband is like a bug magnet (he’s just too sweet!), so an effective bug repellent is incredibly important for his comfort and overall health. We love to go hiking and just be outside, but we sometimes had to limit ourselves to certain times of day to avoid the worst of the bugs. Not anymore!

Liquids for Which There are No Solid Options
Unfortunately, there are some things for which there are no solid options, at least none that I can recommend. The liquids I must take with me when I travel are:
- Contact solution (medically necessary, so does not have to be restricted to the 3.4-ounce rule)
- Hair mousse, gel, foam, etc.
Getting it down to two is pretty good! What liquids do you wish came in a solid form? Would you be willing to go solid with your toiletries? Comment below!
